when the trunnion seat to be heated enters the cabinet body 1, the thermocouple heater 9 at the top of the inner cavity of the cabinet body 1 is electrified and heated and falls into the trunnion seat assembling hole in place downwards through the jacking cylinder, at the moment, the thermocouple heater 9 heats the inner wall of the trunnion seat assembling hole, the assembling hole is expanded through heating the trunnion seat from inside to outside, and when air after being heated and risen downwards enters the heating seat 602 at the bottom side, the butting action of the arc-shaped surface at the inner side of the heating seat 602 drives airflow to reversely and upwards reflux and heat the bottom of the trunnion seat, so that the heating influence of the thermocouple heater 9 at the top on the bottom side of the trunnion seat is reduced, the electric heating pipe and the heating plate 603 in the inner cavity of the heating seat 602 provide heating heat to reheat the refluxed air, and after the trunnion seat is sufficiently heated and generates a thermal expansion effect, the heating work is finished;
after the heating of the heating trunnion seat is completed, the feeding plate 501 moves towards the outer side of the cabinet body 1 by pulling the feeding mechanism 5, when the feeding plate 501 moves to the outer side of the cabinet body 1 and is positioned at the bottom side of the lifting mechanism 2, the positioning seat 401 moves downwards under the driving action of the linear driving part 7 at one side, the linear driving part 7 is preferably a large-torque linear module or a hydraulic driving component, the positioning seat 401 moves to drive the abutting block 404 sliding at the inner side to contact with the outer edge of the top of the outer edge of the trunnion seat, the abutting block 404 is forced to move in the sliding hole through the first sliding rod 405 at the rear side, due to the abutting action of the abutting blocks 404 along the axis, the trunnion seat is extended to the longer position of the outer edge of the positioning seat 401 by the abutting ball 406 at the tail end of the abutting block 404 at the offset position, at the moment, the working piston rod of the hydraulic cylinder shortens the connecting block 303 to pull the resetting press ring 302 to move downwards to drive the resetting press ring 301, and when the resetting mechanism 3 moving downwards along the axis contacts with the abutting block 404 at the offset position, the abutting ball 406 drives the inner abutting block 404 to press the trunnion seat to move and reset to the offset reverse position under the pressing action of the reset pressing ring 301, the trunnion seat calibration is completed at the moment, the hoisted trunnion is downwards dropped into the trunnion seat through the hoisting mechanism 2 to be subjected to interference assembly, the trunnion seat is waited to be removed after being cooled, and the assembly is completed.
